摘要
针对FLAC^(3D)在模拟采场采空区时所面临的问题,在对其软件特征分析基础上,得到了对采场采空区的不同方法,本文对FLAC^(3D)处理采空区的不同方法进行了优缺点及适用性分析,并利用其内置FISH语言进行实现,最后以中煤大屯矿姚桥煤矿地质条件为实例,对不同模拟方法效果对比分析,结果表明,分步开挖软化顶板法并不能准确反映实际采场顶板运动规律,软化采场处理方式较为准确易行。
In view of the problems faced in simulating goaf with FLAC3D software,different methods for goaf analysis are obtained based on the research of its software features.The paper compares the different methods under FLAC3D treatment for goaf in advantages and disadvantages and the applicability with the assist of its FISH language integrated in the software.In the paper,comparison is also carried out in Daitun mine in China coal Group as a case study under the specific geological conditions.The results show that the method of excavation step by step roof-softened can not accurately reflect the laws of actual roof movement in the mining field,the method of softening with water injection are more accurate and easy.
